"I saw some live footage of them, and I was so excited to see a band that was heavy, had riffs, had songs, and could really perform, and an audience that was genuinely excited to watch them play," Grohl said, according to NME.

"And then someone tells me that the album went to number one, and for another guy with a guitar to see another guy with a guitar getting the number one record, it's so encouraging," the American icon continued. "Not that I think that rock 'n' roll is the only type of music, but in this day and age it's good to see it fucking show its face now and then. And it's a good record, I'm excited about that."

It's about rock!
